ᐅ Upgrading underfloor heating with actuators and wireless receivers

Hello, I would like to equip our underfloor heating system with actuators and wireless receivers so that the temperature in the rooms can be controlled using wireless room thermostats. First, a basic question: does the heating manifold also need to be equipped with flow meters for this purpose? Our existing one does not have these meters. A second question: when replacing the actuators, can the old ones simply be removed and the new ones screwed on, or will water leak during this process? Thanks and best regards, Ashley

Not at all. There is no standard case.

Spill the details: what type of underfloor heating? How is it powered? What is the rest of the build like? Keyword: heat loss.

There is a underfloor heating system by Giacomini from around 1993. In the basement, there is a gas boiler. The control valves are located in boxes within the walls on both the ground floor and the first floor. It would be more convenient if these valves did not need to be manually adjusted and instead regulated automatically according to the room temperature.

So far, do you open the box every time and manually adjust the actuator to change the room temperature?
Is the gas boiler also from 1993?
Is the boiler controlled by the outdoor temperature?

1. Basically yes, since we don’t need the same heating level in all rooms throughout the entire heating season.
2. The gas boiler is only a few years old and, in my opinion, has an outdoor sensor.

Yes, just install standard actuators on the heating circuit distributors (these are also available from Giacomini) and suitable wireless thermostats in the rooms.

And of course, a hydraulic balancing would be advisable.

You would definitely need someone on site who is knowledgeable and can retrofit all of this.

No, a hydraulic balancing must be performed first and then controlled via the heating curve.
